Execution process:
The drilling fixed cycle is composed of
the following 6 operations.
Operation 1: X(Z) and C axis (requirement
in some occasion) positions to
the hole position of initial plane;
Operation 2: rapidly traverse to point R;
Operation 3: drilling (cutting feed or interval feed);
Operation 4: pause at the hole bottom;
Operation 5: retract tool to the plane where point R
is;
Operation 6: rapidly traverse to initial plane
